"Beer goggles" is a slang term for a phenomenon in which consumption of alcohol lowers sexual inhibitions to the point that very little or no discretion is used when approaching or choosing sexual partners. It can also refer to literal goggle-like devices used to distort vision to simulate the effects of drunkenness.

The term is often humorously applied when an individual is observed making advances towards, later regretting sexual contact with, a partner that is deemed unattractive, unacceptably scandalous, or repulsive when the prospect of sex is considered while sober. The "beer goggles" are considered to have distorted the "wearer's" vision, making unattractive people appear beautiful, or at least passably attractive.

A study supported the beer goggles theory; however, it also found that another explanation is that regular drinkers tend to have personality traits that mean they find people more attractive, whether or not they are under the influence of alcohol at the time.
